2. Hot water in an open storage tank at 350 K is being pumped at the rate of 0.0040 m3 s-1 from the tank. The line from the storage tank to the pump suction is 6.5 m of 2-in. schedule 40 steel pipe and it contains three elbows. The discharge line after the pump is 70 m of 2- in. schedule 40 steel pipe and contains two elbows The water discharges to the atmosphere at a height of 6.0 m above the water level in the storage tank. a) Calculate the total frictional losses, F of this system. Ans: 122.8 J/KG b) Write the mechanical energy balance and determine the Ws of the pump in J/kg. State Ans: Ws=-186.9 J/Kg any assumption made. c) What is the pump power if its efficiency is 80% ? Ans: 1.527 KW
